What is the mean free path for the molecules in an ideal gas when the pressure is 100 kPa and the temperature is 300 K given that the collision cross-section for the molecules of that gas is 2.0 × 10-20 m2? Boltzmann's constant is k = 1.38 × 10-23 J/K.
Once a traffic light turns green, a car speeds up from rest to 50 mi/h with constant acceleration 9 mi/h • s. In the adjoining bike lane, a cyclist speeds up from rest to 20mi/h with constant acceleration 13mi/h.
